What causes hemorrhoids to bleed?
Internal hemorrhoids can easily cause rectal bleeding. The main reason is the varicosity of hemorrhoidal veins. During defecation, dry and hard stools scratch the hemorrhoidal veins causing them to rupture and bleed. Additionally, due to the long-term presence of hemorrhoids, the hemorrhoidal veins become overstretched, making the vein walls thin and fragile, and easily damaged during bowel movements. For hemorrhoid-induced rectal bleeding, treatment can be administered through medications aimed primarily at reducing bleeding symptoms and alleviating the varicosity of the hemorrhoidal veins. Sitz baths can also be used to reduce swelling around the anus. If medication provides limited relief, minimally invasive or surgical treatments may be considered.
